目前关于口腔运动控制的文献报道了关于正常老化的舌肌中发生的生理、功能和感觉变化的相互矛盾的发现。有人认为，当其他骨骼肌更有可能表现出这种变化的功能效应时，咀嚼和言语中舌肌所需的高水平活动可能在保护它们方面发挥作用。为了测试舌运动是否确实在言语和吞咽任务中保持不变作为老化的函数，舌背运动的运动学测量被作为21名健康的年轻人（20-30岁）和老年人（65-74岁）进行重复迭代的言语任务和连续的水吞咽任务。使用电磁关节造影记录舌头运动，并从这些数据中提取关于运动范围、持续时间和变异性的信息。研究结果表明，一般来说，吞咽时的舌头运动比说话时更慢，更多变，最重要的是，老年人比年轻人更多变。同样，研究结果表明，衰老确实会影响舌头运动的性质，特别是通过诱导言语（变化较小）和吞咽（变化较大）任务的运动变异性的更极端的区别。
Current literature on oral motor control reports contradictory findings regarding physiological, functional and sensory changes that occur in the muscles of the tongue with normal aging. It has been suggested that the high level of activity required of tongue muscles in mastication and speech may play a role in preserving them when other skeletal muscles are more likely to show functional effects of such changes. To test whether indeed tongue movements remain unaltered in both speech and swallowing tasks as a function of aging, kinematic measures of tongue dorsum movements were taken as 21 healthy young (20-30) and older (65-74) adults performed repeated iterations of speech tasks and a sequential water swallowing task. Tongue motion was recorded using electromagnetic articulography and from these data information was extracted with respect to movement range, duration, and variability. The findings suggest that in general tongue movements for swallowing were slower and more variable than for speech, and most importantly, more variable among older than younger participants. As well, the findings show that aging does influence the nature of tongue motions, in particular by inducing a more extreme distinction in the variability of movements for speech (less variable) and swallowing (more variable) tasks.
